26" 7/8/9SPD MTB Wheel Suggestions Wanted

Hey all. Last week you guys were super helpful in explaining to me that I could upgrade my old 26" wheels that have a 7SPD freewheel to a set with a 7/8/9SPD cassette. In an effort to "give back" I've purchased a 1 year subscription to the forum.

This is my city bomber. I like to hop up and off of curbs and occasionally I'll miss a pot hole. So nothing too dainty but they probably don't need to be built like a tank.

I am currently running 26x1.95 Kenda K838 Slick Tires and will never go beyond a 2.0.

My current wheels are Matrix 550 ETRTO 559x20 AL 6061-T6

I don't know much about wheels so I'll say this: quality wise I am looking for something similar to Deore or XT. This is an old entry level bike but it has sentimental value so I don't spending a little money on it.

While browsing online I've seen these wheels:

From Merlin Cycles:
https://www.merlincycles.com/pair-ha...isc-48983.html

From Nashbar: Sun Ringlé Rhyno Lite / Shimano Deore 525
Sun Ringlé Rhyno Lite / Shimano Deore 525 Mountain Wheelset

Any advice or suggestions are greatly appreciated!

Of the two you listed, the Merlin option would be my choice due to it having double butted spokes. Of the rims they offer; I'd go with the wider option (XM719).

Personally; I build my own wheels, and spend more than the options you list just for the components. My 559 rear wheels have these components:
hub: Wheel Master Tandem Rear Hub - 40H, QR, 9-Speed Cassette, Silver
rim: Velocity Aeroheat 26" 40 h Blk Ano/Sil Sided rim
NDS spokes: Wheelsmith DB15 Spokes Double Butted 252mm 15g 1.8/1.5/1.8 Lot of 10 Silver NEW
DS spokes: 35 NEW DB14 Wheelsmith 250m.m. Butted Stainless steel spokes 14ga | eBay

People are giving away 26" rim brake wheelsets and even complete mtn bikes. If you can connect with a club near you I'll bet you could find something nice. Or ask on CL.

nfmisso, I appreciate the suggestion of building my own but I'm not sure I have the knowledge to do that. I true my own rims but that's about it Who knows maybe I'll do some research and give it a try. Do you know of any good tutorials?

I'm going to look into the XM719 that you suggested and maybe pair it with an XT hub.

Unfortunately there's not much for parts on my local craigslist.

If you can true - the hardest part - you can build.

You can get 26 Vuelta ZEROLITE disk or rim brake for under $100 shipped. Nothing great but not bad either for the price. I have a set of Comp SE (rim brake) on my tank hybrid with some 1.75 Marathon tires and no problems.

XT, or better hubs, and a decent Double-walled rim.

Double-butted spokes will NOT improve durability, and weight is not an issue for your use.

and, from your description of your riding... try some narrower tires, 1.5" or less... panaracer Paselas are my choice for paved riding... light weight (less rolling mass!), higher pressure, and they roll nicely! i use the 1.375 ones, and am not a lightweight kinda person... no flats yet!

This is actually incorrect, though in practice neither type should break in a properly designed and built wheel.

ok... explain how a thinner spoke is more durable.

Short version... The thinner spoke is more elastic. This helps at the spoke head's bend by being slightly more gentle WRT the tension and detension cycles.

It's easy to confuse strength and durability. The straight 2.0 mm spoke is stronger, but IME even a DB 1.8-1.6 mm spoke is strong and durable enough for the typical roadie and for me, preferable for non eyeletted rims.

I have two wheel sets with straight 2.0 mm spokes, one on a touring bike and the other on a roadie and they're fine for now. One high milage touring bike I bought still has the OEM straight 1.8 mm wheel set (with two 2.0 mm replacements in the rear).

Yes, thanks Brad. It's one of those things that doesn't sound like it should be true but is.... For the same reason, wheels are sometimes built with a smaller gauge spoke on NDS rear.

look into Metal Fatigue sometime, then realize that you are wrong.

and your reply is telling... the 1.8 mm spokes broke, after repeated "stretching" and flexing... did they break at the j bend, or near the FORMED(rolled) threads? Both are areas of WORK HARDENING, and deformation of material, btw... and the j bend is an area of fracturing of the elongated crystals formed in the material during manufacture of the originally straight wire. Proper alloy selection/quality control of the material will limit, but not eliminate, this micro-fracturing.

look into metallurgy... fascinating stuff!

guess i should ad this... you aren't totally wrong... you are misinformed.... find where you were misinformed. Find some high quality, double-butted, 2.0mm spokes for best results. ;-) And "Double Butted" is a long standing misuse of words, eh?

Maddog, maybe we have misunderstood your position. I responded to your statement "Double-butted spokes will NOT improve durability..." If the choices are a straight gauge or a db in the same size, then the db will be more durable, as Brad explained. This is acknowledged by all spoke manufacturers and AFAIK all competent wheel builders. Plenty of decent wheels have been built with straight gauge spokes but for economic reasons rather than durability, though there may be a use for some really thick spokes that have no db version. I don't have the required education to go on about "metallurgy" but maybe you do. I expect the folks at DT, Sapim, etc. do understand these things so I trust their judgement.
